Zoom in on Kate Middleton's red and green print dress, and you'll find a floral pattern. Sure, the Vanessa Seward number features a festive color scheme, but Kate jazzed up the design to make it holiday appropriate [1]. The duchess joined Prince William and Prince Harry at The Mix in London, where they appeared at the youth charity's Christmas party [2] and promoted their Heads Together campaign.

While plenty are buzzing about Kate's lightweight midi — it's still available to shop [3] and a brand new label for her — we zoomed in on her Alexander McQueen leather belt. In our opinion, it's reminiscent of the one Santa Claus wears, and for that we give Kate's subtle style move an A+.

The rest of the duchess's accessories were equally appropriate, including Catherine Zoraida hoop earrings [4], a Mulberry suede clutch, and Gianvito Rossi pumps. Read on to check out her look from every angle, then shop Kate's dress along with similar options, since we expect this one to sell out soon.
